Using Windows Server 2012 Essentials.
I've got two ethernet ports. One is connected to a router which is connected to the internet. This portion of the network is fine. The router runs DHCP on the 192.168.1.x subnet, and provides a Company1 WiFi for guests, which does not have access to servers etc.
The idea is to have a second LAN, through the Windows server. I'm trying to use the .16.x subnet for this, but machines on teh 16.x subnet can't see the internet.
Port 1 is set to get settings automatically from the router.
Port 2 is configured as so: IP: 192.168.16.101 Subnet: 255.255.255.0 Gateway 192.168.1.101 DNS: 192.168.1.101
This connection shows as limited connectivity on the server.
Clients are set to use 192.168.1.101 as both gateway and DNS. The server provides DNS services and DHCP on the internal network interface. I suspect that either the DNS/Gateway settings on port 2 (Internal) are wrong, but I've tried everything I can think of.
